/proc/swaps is not available in 2.0.x (not in the official kernel,
anyway).

swapoff doesn't know what to swap off, it tries to be smart and look at
fstab, but that obviously fails if you make changes by hand. It is
precisely the reason why /proc/swaps was created.
That's not the point, anyway. The kernel should not depend on user-space
utilities for its sane state. Mind you, counting a file/device twice for
swap is what I would a rather insane setup. :-)
